“It’s a race against time,” said Klaus Jacob, a research scientist at Lamont-Doherty and member of the City’s Panel on Climate Change that came up with the data underlying Mayor Bloomberg's report. “It’s a race of good will against lethargy and complacency. The mayor is certainly gung-ho for this but we have to see what happens after his term is over.”

The first comprehensive survey of all Antarctic ice shelves by researchers at NASA and Lamont-Doherty have found that it is actually a warmer ocean — and not icebergs — that is responsible for the loss of ice-shelf mass that other ongoing research is documenting.

A new study in Science co-authored by Lamont-Doherty scientist Stan Jacobs finds that East Antarctic ice shelves are also losing mass, which can accelerate the flow of continental ice to the sea, contributing to sea-level rise.

A warmer climate leads to drier soils, says Lamont-Doherty scientist Richard Seager, raising the chances that a devastating Dust Bowl-like drought could happen again.

Klaus Jacob, a member of New York City's Panel on Climate Change and a geophysicist at Lamont-Doherty, says the city needs to plan for as much as six feet of sea level rise by 2100.

In today’s Academic Minute, Dr. Dorothy Peteet of Columbia University reveals what the Hudson River has to say about the climate of the past.

Science on the iciest continent sometimes requires high-tech equipment. Other times, just an old time geology tool like a rock hammer will do. "Things that were done in the Appalachians 100 years ago are still needing to be done in Antarctica," said David Barbeau, a geologist at University of South Carolina and currently a visiting scientist at Lamont-Doherty.

During the last ice age, deep Arctic Ocean waters still flowed and flushed sediment out of the basin, a new study co-authored by Lamont's Sharon Hoffmann and Jerry McManus finds, showing that sea ice likely formed and melted like it does today.

Small earthquakes brought on by the Earth's tides could help scientists forecast the next large, destructive earthquake, said Lamont-Doherty geophysicist Maya Tolstoy at a public lecture in Manhattan.

Carbon-dioxide levels have increased every year, and earlier this month they reached the milestone of four hundred parts per million. "It feels like the inevitable march toward disaster," Lamont-Doherty scientist Maureen Raymo told the Times.

Lamont-Doherty scientist Richard Seager expresses doubt that record sea ice loss in the Arctic is responsible for unusually warm and unusually cold winters in parts of North America and Europe.

Rockland County could save 1 to 3 million gallons of water a day simply through better conservation methods, Lamont-Doherty researcher Stuart Braman has found.

Could past periods of warming, which melted back Earth's ice sheets, have triggered volcanic eruptions? Lamont postdoctoral researcher David Ferguson is analyzing rocks from Chile's volcanic rim to find out.

Lamont-Doherty scientist Adam Sobel comments on state of tornado prediction.

The type of tornado that hit Oklahoma could become more common as the atmosphere warms. Or maybe not. Lamont-Doherty scientist Adam Sobel comments on the state of tornado prediction.

A magnitude 4.4 earthquake in Ontario, Canada, was felt early Friday from upstate New York to the Vermont border and recorded on the Lamont-Doherty Cooperative Seismographic Network.

David Ferguson, a volcanologist at Lamont-Doherty, discusses the possibility of humans stopping massive magma flows.

Lamont-Doherty scientist Klaus Jacob discusses the difficult choices New York City must make to confront rising sea levels.

Lamont-Doherty scientist Jason Smerdon speaks with public radio host Kathleen Dunn about C02 surpassing the 400 parts per million mark.

Lamont-Doherty scientist Klaus Jacob explains what went wrong with New Jersey's transit preparations for Hurricane Sandy.
